:-( i came here hoping of #science days like back then on #twitter with #fluorescenceFriday and #MicroscopyMonday .
Instead im choking on #fascism in the world and #genocide .
there was a post some time ago about that online protest 1. doesnt work and 2. paralyzes you, giving you the illusion of being active.
i guess i pretty much failed that.

Whole-mouse imaging the hard way: Clearing, then slicing + block-face imaging with beam-scan / sensor scan-line synchronization and continuous stage movement in an oblique imaging setup (ViSOR).
This time, they scaled it up to whole-mouse and used pre-cleared mouse bodies (ARCHmap-blockface-ViSOR):High-speed mapping of whole-mouse peripheral nerves at subcellular resolution
Shi et al., preprint at biorxiv 2025

Ya boi is back with more microscope photos :3
Here are a few pics of a cool looking filamentous algae I found looking at more bog water under the microscope. I don't know too much about algae species (yet!) so I can't say much in terms of identification for this specimen, but it's certainly pretty to look at!

#MicroscopyMonday – No this is NOT an aerial view of the Grand Canyon.
This is a scanning electron microscopy image of the cranial sutures in the rat skull. 🔬💀🐀 These are fibrous joints where the bones of the skull interdigitate, allowing for flexibility and growth during infancy and early childhood before fusing in adulthood.

Happy #MicroscopyMonday!
Here is a kymograph of a cell crawling into a microchannel. Each horizontal row of pixels represents a line drawn from outside (green) through a channel (purple) at 5 second timepoints. ~1/2 way down (20 min) a cell fully enters the channel and takes off! -

🌟 Pre-vacation #MicroscopyMonday magic rendered by @Daniel_Stabley! 🌟 This is a showstopper: our top plasma membrane probes light up neurons and glia. But wait, there's more! The grand finale? A lattice light sheet stunner showing off its isotropic prowess in the XZ view. Confocal 3D rotations, eat your heart out! 🧠🔬✨ #Neuroscience #MicroscopyMagic #NextLevelImaging #cellbio #cellfie #scicomm #neuroscience #Microscopy

⚠️ That's what a leaky blood vessel looks like in the microscope. Astrocytes (🟡Gfap) around the blood vessel become reactive, inducing neuroinflammatory responses and attacking the surrounding neurons (🔵Neun) in the pathway. #MicroscopyMonday

Ich habe ein bisschen USB 3.0 Kabel zerschnitten und Querschnittsbilder mit dem Mikroskop gemacht. Das Video hat Kapitelmarken für die Eiligen und noch mehr Infos und Links in der Videobeschreibung. Viel Freude!

Es ist zwar nicht Montag, aber ich hab lange nichts mehr zu #MicroscopyMonday gepostet, also:

Let's have a #notthecover for #MicroscopyMonday: hippocampal neuron with endogenously tagged HA-actin — one of the proposed covers for https://rupress.org/jcb/article-abstract/222/10/e202208110/276185/Presynapses-contain-distinct-actin

Im Video seht ihr eine Mikroskopie-Aufnahme von einem Mehrklingen-Rasierer, den ich langsam kippe, so dass man die Schneide-Kante einer der Klingen gut erkennen kann. Das Video stammt aus einem ganzen Mikroskopie-Stream über Messer und Klingen, hier findet ihr einen Zusammenschnitt davon: https://www.youtube.com/watch?v=9LRrt-hsuYk

Heute ist Montag, also auch #MicroscopyMonday
Ich habe mir mal Stifte und die entsprechenden Linien auf Papier unter dem #Mikroskop angeschaut, und das ganze sogar live gestreamt. Auf den Bildern unten seht ihr die Striche auf Papier, eine Kugelschreiber-"Spitze" und eine Nahaufnahme eines Farbdrucks. Maßstab jeweils im Bild. Bilder CC BY 4.0

Heute ist Montag, also auch #MicroscopyMonday
Ich habe mir mal die grauen Reflektorstreifen einer Warnweste unter dem Mikroskop angesehen (war in einem früheren Mikroskop-Stream auf #twitchDE) - diese Reflektorstreifen bestehen aus kleinen Glaskügelchen mit einem Durchmesser von ca. 40-70µm, eingebettet in eine Art Gel.

Happy (or not?) #MicroscopyMonday!
I made a chart out of all the amoeba faces I've found to put on the lab fridge. Unfortunately, happy faces are not an observable phenotype for Naegleria. -

Better late than never for #MicroscopyMonday!
Here is a z-stack (every focal plane moving vertically through a sample) of actin polymer-stained Naegleria amoebae, followed by a maximum intensity projection (the brightest xy point of all the z positions). The darker colors here represent places where there is more actin polymer. -

Here's a movie from the "Titus Takeover" week, where Meg Titus and several million Dictyostelium cells visited the Fritz-Laylin Lab!
Here are 2 movies (1st at 4x, 2nd at 10x) of Dicty cells streaming to form mounds during overnight starvation. -

Here is a projection of 10 minutes of amoebae crawling on glass, so you can see their tracks. Not bad for a 4x objective and transmitted light!LUT: CMOcean, curl

Here's one from my PhD work:
This cell is infected with Enteropathogenic E. coli (EPEC). EPEC translocates its own receptor (Tir, labeled pink) which triggers actin assembly (green) intro protrusive pedestals. -

Here’s a collage I made a while back highlighting Naegleria’s actin (cyan) and microtubule (orange) cytoskeletons. Naegleria only use microtubules to build a mitotic spindle, and when they transiently transform into a flagellated cell type. -

Here is an amoeba crawling through a microchannel. Blue areas show where the cell is in close contact with the coverslip (imaged by IRM), and DIC is shown in grayscale. -

A little late for #MicroscopyMonday, but I still wanted to share this movie of Naegleria's contractile vacuoles that I just finished color coding!

@christlet I’m looking forward to #MicroscopyMonday when they look like this!!! 😍 🤩

Is #MicroscopyMonday a thing here? This image shows a single #neuron where #actin has been tagged (orange), with all neurons of the culture labeled for #microtubules in the cell body and dendrites (map2, blue), and for actin (gray)
